Blueberry plant named &#39;mg11654-24-001&#39;

ABSTRACT

The new blueberry plant variety ‘MG11654-24-001’ is provided. ‘MG11654-24-001’ is a commercial variety intended for the fresh fruit market. The variety is produced from a cross of ‘Duke’ (seed parent, not patented) and ‘Ridley 1403’ (pollen parent, U.S. Plant Pat. No. 25,432), which can be distinguished by its outstanding features.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application No. 62/762,828 filed on May 22, 2018, which is incorporated herein by reference in its entirety as though fully set forth.

Latin name of the genus and species: Genus—Vaccinium. Species—hybrid.

Variety denomination: The new blueberry plant claimed is of the variety denominated ‘MG11654-24-001’.

BACKGROUND OF THE INVENTION

The proposed new variety ‘MG11654-24-001’ was selected as a seedling from a controlled pollination involving northern and southern highbush varieties ‘Duke’ (seed parent) (not patented) and ‘Ridley 1403’ (pollen parent) (U.S. Plant Pat. No. 25,432) respectively. The cross was made in 2011 in Moondarra, Victoria, Australia and the variety was selected in 2014 in Moondarra, Victoria, Australia. This new cultivar has been asexually propagated through cuttings since 2016 and grown in replicated field trials from 2017 in Moondarra, Victoria, Australia. The plants of ‘MG11654-24-001’ are tough and vigorous with an upright to whippy growth habit while the fruit is very crunchy, large and firm with a good flavor and bloom

SUMMARY OF THE INVENTION

As mentioned above, the proposed new cultivar ‘MG11654-24-001’ is a result of a cross between ‘Duke’ and ‘Ridley 1403’, whose characteristics are discussed below.

The seed parent ‘Duke’ is a northern highbush variety with early fruit ripening, high chill requirement and high yields with medium to large fruit and a moderate to strong bloom.

The pollen parent ‘Ridley 1403’ was produced from a southern highbush seedling selection of ‘S02-25-05’ (unpatented) and pollen parent ‘S03-08-02’ (unpatented) and was selected in 2008 at Lindendale, New South Wales, Australia with the criteria of strong plant vigor, early-mid fruit ripening, very large fruit size and very firm/crunchy fruit texture.

The proposed new variety ‘MG11654-24-001’ is a selection from seedlings produced from a controlled pollination between ‘Duke’ and ‘Ridley 1403’ in the breeding program at Moondarra, Victoria, Australia in 2011.

Asexual reproduction of the proposed new variety ‘MG11654-24-001’ by cutting propagation has occurred since 2016 at Moondarra, Victoria, Australia. This has demonstrated that the new variety is uniform, stable and true to type over successive generations of asexual propagation in respect to the characteristics aforementioned.

The proposed new cultivar ‘MG11654-24-001’ was selected as a single plant in a population of seedlings resulting from a cross between ‘Duke’ and ‘Ridley 1403’ and selected in 2014 at Moondarra, Victoria, Australia. The selection of ‘MG11654-24-001; was based upon the characteristics of strong plant vigor and bush toughness, early fruit ripening and large, firm, crunchy berries with a good flavor and bloom. ‘MG11654-24-001’ has been evaluated in field trials since 2017 at Moondarra, Victoria, Australia.

The following characteristics of the proposed new variety have been observed and used to distinguish ‘MG11654-24-001’ as a distinct cultivar of Vaccinium hybrid:

-   -   —Very early-season fruit ripening.     -   —Strong plant vigor.     -   —Upright/whippy growth habit.     -   —Large berry size.     -   —Crunchy berry texture.     -   —Small dry picking scar.     -   —Sweet berry flavor.     -   —Good light colored bloom.

The proposed new variety ‘MG11654-24-001’ differs from the seed parent ‘Duke’ as previously described in terms of ‘MG11654-24-001’ possessing a possible lower chill requirement, very early fruit ripening, large fruit and a crunchy fruit texture.

‘MG11654-24-001’ differs from pollen parent ‘Ridley 1403’ in respect to having an expected higher chill requirement, smaller berry size and reduced plant vigor.

The proposed new variety ‘MG11654-24-001’ is uniform, stable and true to type over successive generations of asexual propagation through softwood cuttings in respect to the characteristics aforementioned.
